Description
In this talk, I will explore a novel way of probing dS horizons using holography. Namely, we studied asymptotically AdS2 solutions that deep in the interior flow to the cosmological horizon of dS2. I will analyse various matter perturbations, both in Euclidean and Lorentzian signature, at linearised and non-linear level. The results can be used to characterise the features of a putative dual quantum mechanics. The chaotic nature of the de Sitter horizon will be assessed and compared to the usual black hole case. The talk will be based on 1811.08153 and work in progress with D. Anninos and D. Hofman.
